Abstract
The utility model discloses a rear coaming structure which comprises a rear coaming inner plate and a rear coaming outer plate, which are welded together, and the side surfaces of the rear coaming inner plate and the rear coaming outer plate are connected through a connection board. An internal space formed by the rear coaming inner plate, the rear coaming outer plate and the connection board is a through C-shaped cavity, and the interior of a rear coaming assembly is a C-shaped cavity. The rigidity and strength of the assembly is improved, the internal portion of the rear coaming is formed by welding three portions, and die cost is lowered. Cavity is arranged between an installation reinforcing plate of a rear crashproof beam and the rear coaming inner plate, which increases the installation structural strength of the rear crashproof beam. With such an improvement, the rear coaming structure is easy for installation and is light.
Description
Technical field
The utility model relates to automobile body-in-white parts, specifically a kind of rear end panel structure.
Background technology
Current auto consumer is more and more paid attention to the safety performance of automobile, and as the body in white structure of bringing into play main energy-absorbing protective effect in the collision process particular importance that just seems, improve the safety performance of body in white structure, making it have enough stiffness and strengths also comes into one's own more, rear end panel assembly is as component part important in body in white, it is mainly sealing body tail space, with floor, the environment parts such as gusset form boot, in the time manufacturing and designing, just require enough rigidity, intensity, and the overall collision performance target of body in white is contributed, simultaneously in the rear impact test of evaluation new car safety performance grade, rear end panel also plays an important role.And lightweight is the trend of modern automobile manufacturing.
Utility model content
For the deficiency in background technology, the purpose of this utility model is to provide a kind of rear end panel structure, not only can meet the required intensity of assembly, rigidity property requirement, failure-free installation environment can also be provided and take into account lightweight index.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rear end panel structure, comprise back wall inner panel and the rear wall outer plate of weld together, it is characterized in that: the side of described back wall inner panel and rear wall outer plate is connected by connecting panel, and the inner space that described back wall inner panel, rear wall outer plate and connecting panel form is the C die cavity body connecting.
Preferably, be provided with back door snap close and strengthen version in described cavity, described back door snap close is strengthened version and is welded on described back wall inner panel middle part.
Preferably, be arranged with back buffer beam brace panel is installed in described cavity, described back buffer beam is installed brace panel and is welded on described back wall inner panel, and is provided with die cavity between back wall inner panel and back buffer beam installation brace panel.
Preferably, described back wall inner panel comprises line part and the side round part that is provided with turning; Described line part two ends are all connected with side round part; One side of described side round part is connected with described line part, and opposite side is connected with described connecting panel.
The beneficial effects of the utility model are: in rear end panel assembly, be a C die cavity body, improved rigidity, the intensity of assembly; Simultaneously back wall inside is divided into three parts and closes weldering and form, the die cost of reduction; Back buffer beam is installed between brace panel and back wall inner panel and is provided with die cavity simultaneously, has improved the mounting structure intensity that back buffer beam is installed; Finally, by above-mentioned improvement, it is more convenient not only to install, and has also realized weight-saving demand.

The specific embodiment
As shown in Figures 1 to 4, wherein the black heavy line in Fig. 1 is the profile schematic lines of C die cavity body; A kind of rear end panel structure of the utility model shooting, comprise back wall inner panel 1 and rear wall outer plate 2, the side of described back wall inner panel 1 and rear wall outer plate 2 is connected by connecting panel 3, end face beyond described back wall inner panel 1 and rear wall outer plate 2 tops, place is welded to connect, and the inner space that described back wall inner panel 1, rear wall outer plate 2 and connecting panel 3 form is the C die cavity body connecting.In described cavity, be provided with back door snap close and strengthen version 4, described back door snap close is strengthened version 4 and is welded on described back wall inner panel 1 middle part.In described cavity, be arranged with back buffer beam brace panel 5 is installed, described back buffer beam is installed brace panel 5 and is welded on described back wall inner panel 1, and back wall inner panel 1 and back buffer beam are installed between brace panel 5 and be provided with die cavity, described die cavity can be welded on the up one-tenth of back wall inner panel by U-shaped back buffer beam being installed to reinforcement version.Described back wall inner panel 1 comprises line part 1.1 and is provided with the side round part 1.2 at turning; Described line part 1.1 two ends are all connected with side round part 1.2; One side of described side round part 1.2 is connected with described line part 1.1, and opposite side is connected with described connecting panel 3.
First three parts of back wall inner panel are welded into back wall inner panel, and back door snap close brace panel are welded on to the middle part of back wall inner panel, back buffer beam is installed to brace panel and be symmetrically welded at back door snap close brace panel weldering both sides, from then forming back wall inner panel assembly; Then rear wall outer plate and connecting panel are welded into rear wall outer plate assembly; Finally back wall inner panel assembly and rear wall outer plate assembly are closed to weldering for rear end panel assembly, and by rear end panel assembly very elder sister after lower body on floor.
What rear end panel assembly inside adopted is the C die cavity body connecting, and has increased overall Rigidity and strength, is both and has brought lightweight benefit.And back buffer beam is strengthened being also provided with die cavity between version and back wall inside, has increased the intensity with back buffer beam mounting structure.
